OVERVIEW

The Americans with Disabilities Act (ADA) provides specific guidelines and requirements that must be met in terms of accessibility.  However, in the case of unpaved trails, the requirements are less defined.  An ADA trail must be firm, stable and slip resistant.  Some compacted aggregate material may meet this definition, but degrade over time and can no longer be ADA compliant.  The benefits of using unpaved surfaces for ADA trails include fit to the natural environment, cost, sustainability and environmental benefits such as increased permeability.  If an unpaved surface can be improved with the use of an additive, more could be used as ADA accessible trails. An earlier NITC study examined The Use of Mt. Mazama Volcanic Ash as Natural Pozzolans for Sustainable Soil and Unpaved Road Improvement. This followup study set out to determine the least amount of portland cement or lime that can be used with this natural pozzolan to create an aggregate binder. This webinar will share the results of that work.

The National Institute for Transportation and Communities (NITC) program has released its 2020 general research request for proposals. Faculty at NITC's partner universities* are invited to submit abstracts by March 23, 2020.


Through funding provided by the U.S. DOT, we will award up to $1,000,000 to research projects that support NITC’s theme: improving mobility of people and goods to build strong communities. Our theme includes a few key topics:

Increasing access to opportunities.

Well-connected regions and communities can improve social equity by providing access to jobs, services, recreation, and social opportunities. Research should examine barriers to access, including the connections between transportation, land use, and housing. It should look at how to overcome these barriers and improve accessibility, affordability, and equity in our communities.

Improving multi-modal planning and shared use of infrastructure.

Improved mobility requires a range of options for moving people and goods. As concepts of mobility evolve, research is needed to understand how people and firms make mode choices so that we can design better multi-modal systems. Research should examine how different modes can share our infrastructure safely. It should look at...

Sep 20, 2018

We held our annual flagship professional development event, Transportation & Communities, on September 13 and 14. In honor of the event's ten-year anniversary, we changed up the format: Rather than a typical conference with one-hour sessions and a keynote gathering, we offered a selection of intensive half-day workshops. See photos from the event.

The workshops gave practitioners a chance to take a deep dive into new skills in order to walk away with new tools or frameworks that could be applied to their work. We offered a review of congestion mitigation strategies, universal access and equity in pedestrian planning, and discussion on how smart technology could be implemented in suburban communities. Several workshops were based on findings from new research by the National Institute for Transportation & Communities (NITC), the six-university consortium which sponsored the event. The NITC...

The National Institute for Transportation and Communities (NITC) is soliciting proposals for our two 2018 Pooled Fund projects:

RFP now open; proposals due Oct 1, 2018

This project will address the need of cities and municipalities to combine bicycle data from different sources (such as manual counts, automatic counts, and crowd-sourced data from apps such as Strava) to assess an accurate accounting of bicycle traffic on a network. Current work on data fusion techniques is limited and additional research is needed to fully understand the choice of weighting techniques, inclusion of spatial vs. temporal variation in the weighting scheme and exploring other...

TEACHING MODULE

Looking for a simple lesson plan outline? Here's a snapshot of the curriculum developed by this project, for faculty who might be interested in incorporating it into their transportation courses.

OVERVIEW

Vehicle operating dynamics data have a fundamental impact on the design of roadways, but collecting this type of data is not part of your typical college curriculum. Instead, engineering students are handed a textbook, leaving them without a firsthand experience of how accelerations and decelerations “feel” to the driver, the ultimate consumer of their designs. Seeking to change this norm, Roger Lindgren and C.J. Riley, civil engineering professors at the Oregon Institute of Technology, undertook a NITC education project to incorporate more real-world data collection and analysis into transportation courses. This...
